Don’t trust the preamble.. Most of the GIT sources haven’t updated them, effectively making those tags useless.

I've run into this before too. It can also be controlled by a "Contact" object in AD, overriding the global settings from Exchange. Outlook thinks it's an internal object at that point and blissfully sends in rich text. Very annoying to track down sometimes, especially when you're trying to prevent TNEF from escaping out to the Internet.
